Go4Expert - VB.NET Selective Code Activation???

Just to make sure I'm understanding the question, your wanting to have 1 button work with 2 different file formats, but not at the same time? If that's correct there's a few different ways to go about this depending on what your wanting. Since your going to have different instructions depending on the file format your working with, I would create a function for each file format that you want to use and if your wanting to only work on 1 file format at a time, i would have radial buttons for you to tell the program which way to go about it. So for this it would be something like:

Code:

Public Class Form1

    'I'm setting these to global variables so you don't have to redefine them for each function

    Dim excelFile As String = "C:\file1.xlsx" 'string to read to your excel file. Change accordingly 

    Dim notepadFile As String = "C:\file1.txt" 'string to read your text file. Change accordingly 

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        'You have to make 2 radial buttons named excelRBTN and notepadRBTN or just change the names in here



        'Check if our excel radial button is checked, if yes then execute

        If excelRBTN.Checked = True Then

            excelFunction() 'Call all statements in this function

            'You could just use Else instead of Elseif but this will be executed anytime you press the button and excelRBTN is not checked.

            'If notepadRBTN is checked, execute.

        ElseIf notepadRBTN.Checked = True Then

            notepadFunction() 'call all statements in this function

        End If





    End Sub



    Function excelFunction()

        'Statements to execute for your excel file

        'I put a messagebox in here to show you how it works

        MessageBox.Show("Excel function executed")

    End Function



    Function notepadFunction()

        'Statements to execute for your notepad file. 

        MessageBox.Show("Notepad function executed")

    End Function

End Class

Just throw that into your compiler and run it to see how it works. From there alter to use for your needs. I wrote this in VS 2008
